"Made an appt. with Castle Rep, James, for 17 windows and vinyl siding. He spent 1 hour talking about how great his company and windows are before finally getting down to the issue. We were told that CASTLE makes and services their own window, with all the best technology and technicians available. The price per window for energy efficient came out to over $1,200 per double-hung window! And since they make their own products, we could not find a way to compare quality and price with other manufacturers. But his per-window price exceeds the average price of $500-700 by A LOT! When we balked, he made a call to his "manager" to see if we qualified for a "special promotional" discount. If we were to commit right there on the spot, we would get an additional 10% off! Still way to high. We said we would think about it (he got sad and snippy), and that we wanted to hear about the vinyl siding quote before we made any decisions. He told us he could not give us a siding quote until his company did an "eagle view" measurement, which would require another appointment! We had no intention of sitting through ANOTHER high-pressure appointment. High pressure, long-drawn out presentation and he would not leave us with anything in writing! No brochures, prices, nothing! He refused to put anything in writing and we could not have a break down of labor and costs. I even asked him if I could have a copyhh of the window warranty and he said "only if you purchase right now." And they did not come prepared with references or previous job locations! When we further researched the company, we found they did make very excellent products, but the #1 complaint was by far that they did not honor their lifetime warranty and that customer service was horrible. In the end, we chose not to do business.."

"Sergio installed a new tile countertops and stone backsplash in my kitchen. His work was perfect! He was easy to contact (Thank you, Monique), prompt, courteous, started the job right on time, stayed with it until it was finished, also right on time, and his price was very reasonable. I had one tiny thing I wanted changed and he took care of it right away and without complaint. I recently needed his help to finish a job started by someone else and he was there within 48 hours! My house is 97 years old, and over the past 20 years, I've worked with many contractors , but Sergio was by far the best. I would recommend him without reservation."

Glass Block Windows questions, answered by experts

Regular cleaning with non-abrasive cleaners helps prevent buildup and maintains clarity.

Luckily, glass block windows need minimal maintenance. Other than regular cleaning, the only maintenance involved in having a glass block window is inspecting for cracks every year and applying sealer to the mortar joints if the blocks are set in masonry mortar. Glass block windows hold up well against wind and moisture better than traditional windows and are not prone to rot.

DIY is possible for small projects, but professional installation ensures proper sealing, structural integrity, and a precise finish.

Glass block mortar is the best choice for glass block window units. It is specifically formulated for glass block window installation. Glass block mortar is usually a mixture of Portland cement, sand, and special chemicals. It is a white mortar that is applicable inside and outside your home. Do not use regular tile mortar because it may not have the binding strength and flexibility required for glass block windows.

Most installations take 1-3 days, depending on the number of blocks and customization requirements.
